specification.

This invention relates to machinery for folding and imprinting or embossing envelops, and in particular tothat class of envelop machinery where the embossi is done in. an envelop machine which fol owe the general lines, and is an improvement upon what is known. as the Rea envelop folder, which was patented in 1865i My invention has for its object to provide means whereby the envelop blank may be embossed while it is in position for the plunger to fold the same; further, to provide cushioned embossing means whereby the paper is preserved; and further, to rovide other improvements in the construc ion of such machines hereinafter set forth.

In the accompanying drawi s is illustrated a desirable embodiment o m] invention. of part ofan envelop machine having my invention applied thereto. Parts of the ma chine are omitted. Fig. 2 is a plan view of the same.

The general method of operation of the machine is to pick up the envelop blank by means of the pickers which gum it and deposit it upon the carriage, then it is carried beneath the plunger and beneath the embossing counter, and when in position beneath the plunger, it is in position for the embossing guide to imprint the flaps.

Accordin to my invention a main "shaft A is provi ed which carries an eccentric S riage W and carries the blank W to position beneath the plunger X. While the blank is held in such position, imprint cam B on the shaft A through suitable mechanism causes an embossing die to emboss the blank. Adjustable means are provided for limiting the travel of the carriage, and

ere, Figure 1 shows a side e ovation action of theembossing die operating mechanism and for adjustingv the imprinter frame.

A detailed description is as follows :-The carriage W for the envelop. machine is moved by the eccentric S which is mounted 'upon the driving shaft A. Surrounding the eccentric S is the yoke S which is rovided' with springs S to adapt itself to t e varying positions of the eccentric S and to ermit the operation of means for regula ing the travel of the carriage. Yoke S is connected b means of the right and left hand threade' adjusting ro S with the lever arm T, and is adjustab e within the slot T throu h bracket T in which it is threaded means are also provided for cushioning the and w ich'ismounted insaid slot; The lever arm Tis clamped upon the rock shaft T by means of the binding screw T U on the same shaft T? is a rockin stop arm having adjustable screw T w ich comes against frame F. It is possible to regulate the throw of this eccentric S and obtain any desir position at the end of the throw, by adjustment of the bracket T in slot T and of the stop arm screw T. Springs 8* permit such variation in the movement of the carriage operatin devices. The lever arm U is also clampe upon the rock shaft T, and its upper end is connected by means of a short re and pins U to the link V. The link V connects with the carriage 'W bearing the envelop W by means of the stud V The carriage W slides upon the rods W and carries the envelop W. The driving shaft A also carriesan imprint cam B. This cam B engages with an arm ofrock lever C through t e rollD. The rock lever C rocks about a shaft E suitably supported in the frame F as by the brackets F The rock lever C on its end opposite the roll Dis Slotted at G to receive the adjustable stud H, whereby an adjustable connection is provided with link I.-

The link I is provided at its lower end with the-link heads I carrying studs H, and thereb the link I is rendered adjustable upon t e lever C so as to increase or diminnected to the imprint lever N which has a forked end formed of arms 'n. n which are trunnioned in a swivel block M which slides upon said link I. This block is maintained in position by adjustable nuts L and K. Between the said block and the nuts K 'a pressure adjusting spring J is coiled about the said link, which provides a cushion to prevent the movement of the imprinter actuating devices from injuring the paper and permits the pressure on the die to be in creased 0r diminished as desired byadjust: ing nuts L.

Imprint lever N bears upon plun er 0, slidably supported in imprinter head the lower end of which plunger carries the counter Q, bearing the matter which it is desired to imprint upon the envelop. A spring 0 coiled about the plunger 0 serves to retract same upon lifting of the imprint lever T.

The machine table P is reinforced with the brackets'P The imprinter head Q, is mounted on imprinter frame Q which is mounted upon the table P, and said frame can be raised or lowered by the adjusting screws Q and it is held in place by adjustable studs Q of which four are illustrated, one on each side of each of the screws Q By these means the imprinter frame is raised or lowered as desired. The imprint head Q, is fastened to this frame and carries the imprint die Q and also the two guides R R The imprinting is so timed that as the plunger 0 leaves the envelop W the envelop machine plunger X operates to form the envelop. In this manner the envelop is mechanically imprinted upon or embossed and completely folded, both operations be ing completed within such a short space of time and for all intents and purposes, are done practically at the same time.

The operation of this device is as follows :The rotation of the driving shaft A through cam S causes the link U to move the carriage IV so that the blank W is in position beneath the embossing counter Q The length of the carriage stroke may be varied to suit different sizes of blanks by adjustment of set screw T. A continued rotation of the driving shaft A brings the iniprint cam B into engagement with the r ll D of the lever arm C. The rod I is thereupon thrust upward and the imprint 'lcver N being fulcrumed in the imprint head Q forces downward the plunger 0 and bears the imprint die Q, against the envelop sheet W supported beneath the same on the disk Q from which position it is'retnrned by spring 0 VVhen-the imprint cam B passes out of engagement through the roll D, the plunger X is caused to operate to form the envelop.

By the use of the above described mochanism the paper out will not be held so tightly and will not be strained or inturn I claim and desire tov protect as the essential features of my device as follows.
